Availability

FreeBSD 8.2-RELEASE is now available for the amd64, i386, ia64, pc98, powerpc, and sparc64 architectures.

FreeBSD 8.2 can be installed from bootable ISO images or over the network. Some architectures (currently amd64 and i386) also support installing from a USB memory stick. The required files can be downloaded via FTP or BitTorrent as described in the sections below. While some of the smaller FTP mirrors may not carry all architectures, they will all generally contain the more common ones such as amd64 and i386.

MD5 and SHA256 hashes for the release ISO images are included at the bottom of this message.

The purpose of the images provided as part of the release are as follows:

dvd1
This contains everything necessary to install the base FreeBSD operating system, a collection of pre-built packages, and the documentation. It also supports booting into a “livefs” based rescue mode. This should be all you need if you can burn and use DVD-sized media.

disc1
This contains the base FreeBSD operating system and the documentation packages for CDROM-sized media. There are no other packages.

livefs
This contains support for booting into a “livefs” based rescue mode but does not support doing an install from the CD itself. It is meant to help rescue an existing system but could be used to do a network based install if necessary.

bootonly
This supports booting a machine using the CDROM drive but does not contain the support for installing FreeBSD from the CD itself. You would need to perform a network based install (e.g. from an FTP server) after booting from the CD.

memstick
This can be written to an USB memory stick (flash drive) and used to do an install on machines capable of booting off USB drives. It also supports booting into a “livefs” based rescue mode. The documentation packages are provided but no other packages.

As one example of how to use the memstick image, assuming the USB drive appears as /dev/da0 on your machine something like this should work:

# dd if=8.2-RELEASE-amd64-memstick.img of=/dev/da0 bs=10240 conv=sync
Be careful to make sure you get the target (of=) correct.

FreeBSD 8.2-RELEASE can also be purchased on CD-ROM or DVD from several vendors. One of the vendors that will be offering FreeBSD 8.2-based products is:

FreeBSD Mall, Inc. http://www.freebsdmall.com/

BitTorrent

8.2-RELEASE ISOs are available via BitTorrent. A collection of torrent files to download the images is available at:

http://torrents.FreeBSD.org:8080/

Updates from Source

The procedure for doing a source code based update is described in the FreeBSD Handbook:

http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/synching.html

http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html

The branch tag to use for updating the source is RELENG_8_2 for CVS. For SVN use releng/8.2.

FreeBSD Update

The freebsd-update(8) utility supports binary upgrades of i386 and amd64 systems running earlier FreeBSD releases. Systems running 7.[01234]-RELEASE, 8.[01]-RELEASE, 8.2-BETA1, or 8.2-RC[123] can upgrade as follows:

# freebsd-update upgrade -r 8.2-RELEASE
During this process, FreeBSD Update may ask the user to help by merging some configuration files or by confirming that the automatically performed merging was done correctly.

# freebsd-update install
The system must be rebooted with the newly installed kernel before continuing.

# shutdown -r now
After rebooting, freebsd-update needs to be run again to install the new userland components:

# freebsd-update install
At this point, users of systems being upgraded from FreeBSD 7.4-RELEASE or earlier will be prompted by freebsd-update to rebuild all third-party applications (e.g., ports installed from the ports tree) due to updates in system libraries.

After updating installed third-party applications (and again, only if freebsd-update printed a message indicating that this was necessary), run freebsd-update again so that it can delete the old (no longer used) system libraries:

# freebsd-update install
Finally, reboot into 8.2-RELEASE:

# shutdown -r now
Support

The FreeBSD Security Team currently plans to support FreeBSD 8.2 until February 29th, 2012. For more information on the Security Team and their support of the various FreeBSD branches see:

FreeBSD 8.2-RELEASE Release Notes

Release Highlights

The highlights in the 8.2-RELEASE are the following:

[amd64] FreeBSD/amd64 now always sets the KVA space as equal to or larger than physical memory size. This change would help to prevent a “kmem_map too small” panic which often occurs when using ZFS.[r214620]

The FreeBSD GENERIC kernel is now compiled with KDB and KDB_TRACE options. From 8.2-RELEASE the kernel supports displaying a stack trace on panic by using stack(9) facility with no debugger backend like ddb(8). Note that this does not change the default behaviors of the GENERIC kernel on panic.[r214326]

The FreeBSD crypto(4) framework (opencrypto) now supports XTS-AES (XEX-TCB-CTS, or XEX-based Tweaked Code Book mode with CipherText Stealing), which is defined in IEEE Std. 1619-2007.[r214254]

[amd64] Xen HVM support in FreeBSD/amd64 kernel has been improved. For more details, see xen(4) manual page.[r215788]

FreeBSD now fully supports GPT (GUID Partition Table). Checksums of primary header and primary partition table are verified properly now.[r213994]

[amd64, i386] The aesni(4) driver has been added. This supports AES accelerator on Intel CPUs and accelerates AES operations for crypto(4).[r215633]

[amd64, i386] The aibs(4) driver has been added. This supports the hardware sensors in ASUS motherboards and replaces the acpi_aiboost(4) driver.[r210476]

The tpm(4) driver, which supports Trusted Platform Module has been added.[r215036]

The xhci(4) driver, which supports Extensible Host Controller Interface (xHCI) and USB 3.0, has been added.[r215944]

The FreeBSD Linux emulation subsystem now supports the video4linux API. This requires native video4linux hardware drivers such as the ones provided by multimedia/pwcbsd and multimedia/webcamd.

The miibus(4) has been rewritten for the generic IEEE 802.3 annex 31B full duplex flow control support. The alc(4), bge(4), bce(4), cas(4), fxp(4), gem(4), jme(4), msk(4), nfe(4), re(4), stge(4), and xl(4) drivers along with atphy(4), bmtphy(4), brgphy(4), e1000phy(4), gentbi(4), inphy(4), ip1000phy(4), jmphy(4), nsgphy(4), nsphyter(4), and rgephy(4) have been updated to support flow control via this facility.[r211379, r215881, r215890, r2105894, r216002, r216023, r216029, r216031, r216033]

A new netgraph(4) node ng_patch(4) has been added. This performs data modification of packets passing through. Modifications are restricted to a subset of C language operations on unsigned integers of 8, 16, 32 or 64-bit size.[r209843]

The FreeBSD TCP reassembly implementation has been improved. A long-standing accounting bug affecting SMP systems has been fixed and the net.inet.tcp.reass.maxqlen sysctl(8) variable has been retired in favor of a per-connection dynamic limit based on the receive socket buffer size. FreeBSD receivers now handle packet loss (particularly losses caused by queue overflows) significantly better than before which improves connection throughput.[r214865, r214866]

The siftr(4), Statistical Information For TCP Research (SIFTR) kernel module has been added. This is a facility that logs a range of statistics on active TCP connections to a log file. It provides the ability to make highly granular measurements of TCP connection state, aimed at system administrators, developers and researchers.[r214859]

The geli(8) GEOM class now uses XTS-AES mode by default.[r214405]

The ZFS on-disk format has been updated to version 15 and various performance improvements for the ZFS have been imported from OpenSolaris.

Userland support for the dtrace(1) subsystem has been added. This allows inspection of userland software itself and its correlation with the kernel, thus allowing a much better picture of what exactly is going on behind the scenes. The dtruss(1) utility has been added and libproc has been updated to support the facility.[r214983]

The gpart(8) utility now supports a recover subcommand for GPT partition tables.

The gpart(8) utility now supports GPT_ENT_ATTR_BOOTME, GPT_ENT_ATTR_BOOTONCE, and GPT_ENT_ATTR_BOOTFAILED attributes in GPT. The attribute keywords in the command line are bootme, bootonce, and bootfailed respectively.[r213994]

The libarchive library and tar(1) utility now support LZMA (Lempel-Ziv-Markov chain-Algorithm) compression format.[r213667]

The newsyslog(8) utility now supports an -S pidfile option to override the default syslogd(8) PID file.[r211699]

The newsyslog(8) utility now supports a special log file name for processing file inclusion. Globbing in the file name and circular dependency detection are supported. For more details, see the newsyslog.conf(5) manual page.[r215622]

The pmcstat(8) utility now supports a file and a network socket as a top source. This allows top monitoring over TCP on a system with no local symbols, for example.[r211098]

The tftp(1) and tftpd(8) utilities have been improved for better interoperability and they now support RFC 1350, 2347, 2348, 2349, and 3617.[r213036, r213038]

A periodic script for zfs scrub has been added. For more details, see the periodic.conf(5) manual page.

A periodic script which can be used to find installed ports’ files with mismatched checksum has been added. For more details, see the periodic.conf(5) manual page.

The sysinstall(8) utility now uses the following numbers for default and minimum partition sizes: 1GB for /, 4GB for /var, and 1GB for /tmp.[r211007]
